Scientific paper

We propose two models, based on the hadronic beam-cloud collision, for production of TeV gamma -ray flares in blazars. In the first model, a change in bulk Lorentz factor of the jet of the Active Galactic Nucleus (AGN) produces the flare. In the second model we consider a two-stage mechanism for high-energy particle acceleration in the jet. This system produces a power law spectrum with two different power indices at low and high energies, which is more efficient than one-stage shock acceleration at high energies. Using this spectrum in a hadronic beam-cloud model for gamma -ray emission of blazars, a variable TeV as well as a stable GeV gamma -ray flux is predicted. The break energy in the spectrum, related to distance between the jet base and terminal shock or boundary layer thickness, is the parameter used to obtain TeV flares.
